Alzheimer’s Disease Risk Factors

Age
Age is a risk factor for AD. The prevalence of AD doubles every five years after the age of 60.

Family history

A family history of AD is a consistent risk factor, and represents around a fourfold increase in the risk of developing the disease. It is thought that as many as… Alzheimer’s Disease Risk Factors   



Alzheimer’s Gene Causes Brain’s Blood Vessels to Leak, Die

A well-known genetic risk factor for Alzheimer’s disease triggers a cascade of signaling that ultimately results in leaky blood vessels in the brain, allowing toxic substances to pour into brain tissue in large amounts, scientists report May 16 in the journal Nature.

The results come from a team of scientists investigating why a gene… Alzheimer’s Gene Causes Brain’s Blood Vessels to Leak, Die   



Women Have Higher Genetic Risk of Alzheimer’s

A major genetic risk factor for Alzheimer’s disease - the E4 variant of the apolipoprotein E (APOE) gene - manifests itself more often in women than in men, researchers reported.

In a cohort of cognitively healthy older men and women, carrying the E4 variant was associated with deficits in brain connectivity in women, but… Women Have Higher Genetic Risk of Alzheimer’s
